This tube is potentially hazardous when broken: see qualified medical personnel and the safety director if you are exposed to or cut by broken tubes. Use extreme care in repl

3、acing these tubes (para 87) and follow safe procedures in their handling, storage, and disposal (para 38.3) Never place radioactive tubes in your pocket. Use extreme care not to break radioactive tubes while handling them. Never remove radioactive tubes from cartons until ready to use them. Refer to

4、 paragraph 38.3 on handling, storage, and disposal of radioactive material. WARNING DANGEROUS VOLTAGES EXIST IN THIS EQUIPMENT Be extremely careful when servicing the power supplies and transmitter; voltage above 450 volts may be present. Take care not to contact the ac power source when connecting

5、power supplies; voltages up 260 may be encountered. WARNING When selenium rectifiers fail because of burnout or arc-over, poison fuses and component fumes and compounds are released. The fumes have a strong odor and must not be inhaled. Provide adequate ventilation immediately and do not handle the

DESCRIPTION AND DATA 3. Purpose and Use a.Radio Set AN/GRC-109 is a compact, portable radio station used for con

20、tinuous wave (cw) communications, at distances up to 75 miles, under a wide range of climatic conditions. Two power supplies and a voltage regulator permit operation from a variety of power sources. b.Only cw signals can be transmitted, but amplitude-modulated (am) voice and tone signals as well as

21、cw signals can be received. Transmissions Change 6 3 TM 11-5820-474-14 can be made by use of a built-in hand key, an external hand key, or an external high-speed, automatic keyer. 4.
